Yeah this one is a bit sad because this particular doodle appear to have no relevant transparency, so those extra parameters should not have caused it to fall back to a static doodle.

I'm already on it. In theory it should have worked -- the doodle is available with all required background types. The issue is that for some reason (yay data), our plugin sees all optional data fields set (even to default values). Unfortunately, our check for transparent background was implemented via !image.hasBackgroundColor() instead of image.getBackgroundColor().empty().
Working on a fix...

Moving this nonessential bug to the next milestone.

Just verified the fix with today's animated Doodle in France:

Keeping this bug open until we could confirm it on a mobile device end-to-end.

This didn't require any client-side fixes, right? Did you get a chance to verify it?

no client side fixes required. Unfortunately, couldn't verify on the device due to lack of doodles. :-/

Verified by Bernhard as part of Issue 625790 for both CTA and animated Doodle.
